Spacer FAQ’s



A nebuliser is a medical device which is intended for delivering asthma and COPD medication where a pressurised metered dose inhaler (pMDI) or puffer and a spacer cannot be utilised by a patient. A nebuliser works by nebulising medication to deliver a fine mist for respiratory therapy and should only be used on the advice of a Doctor or a Healthcare Professional.


Talk to your Doctor or a Healthcare Professional to determine if this is the right product for you.

Always read and follow the instructions in the Instruction Manual on trouble shooting your Breath-A-Tech® Portable Nebuliser.

There could be various reasons which may explain why your Breath-A-Tech® Portable Nebuliser is not working properly. This may depend on factors, such as:

  • When you purchased your Breath-A-Tech® Portable Nebuliser unit

If you purchased and have been using your Breath-A-Tech® Portable Nebuliser for longer than 12 months, then you should replace your Medication Cup within 12 months.

  • Is there enough solution in the medication cup?

It is important to tilt the device slightly until the solution is almost exhausted to make sure that the residual solution contacting the mesh is nebulised completely.

High viscosity solution may result in poor nebulisation or clogging of the mesh. In this case, turn off the power and remove the accumulated solution on the mesh with a gauze or lint free towel.
